胫骨后外侧平台骨折是目前创伤骨科治疗难点和热点之一。因腓骨小头遮挡,后外角韧带复合体、邻近腓总神经和腘血管限制使得该部位骨折难以显露和固定。入路选择和治疗方法存在很大争议。因此,需要熟悉治疗此类骨折的手术入路及其特点。临床关注的入路主要包括:改良的前外侧入路(Gerdy结节截骨,腓骨头截骨,股二头肌腓骨头截骨,股骨外上髁截骨),后外侧入路(Carlson后外侧入路,经腓骨颈截骨及腓骨小头上)及后内侧入路。胫骨后外侧平台骨折入路需要考虑骨折类型、其他象限受累情况、局部软组织条件及所用内固定进行确定。需要考虑体位、骨折形态、内固定生物力学稳定性对治疗的影响。根据文献报道提出累及后外象限的胫骨平台骨折入路选择和内固定流程。 相似文献

胫骨平台后外侧塌陷骨折手术时,传统的前外侧入路因显露不佳使学者近年来多采用后外侧入路或行腓骨小头截骨入路[1]。但膝关节后外侧入路解剖复杂,损伤血管神经可能性大,而且出于保护胫前动脉需要不能向下过度延长切口。笔者自2009年5月~2012年7月尝试采用胫骨前外侧截骨开门法治疗胫骨后外侧平台塌陷骨折21例,安全有效,报告如下。 相似文献

PurposeThe authors have identified a subset of unicondylar tibial plateau depression fracture patterns caused by a flexion-valgus force. The purpose of this study was to describe this fracture pattern and suggest a modified lateral approach that may allow for improved reduction and stabilization.MethodsThe preoperative radiographs and CT scans of 102 patients who sustained unicondylar tibial plateau fractures (OTA 41B) were reviewed. Twenty-six fracture patients had posterolateral (PL) tibial plateau depression fractures. By medical record review and telephone follow-up, the injury mechanism of the 22 unicondylar tibial plateau fractures was confirmed as a flexion-valgus force. The radiographic features of those cases were analyzed and measured. To address this specific fracture pattern, a modified approach combined with a novel intra-articular osteotomy was applied.ResultsAccording to the morphological characteristics, this tibial plateau fracture pattern could be divided into two subtypes: type A was a confined, basin-like articular surface depression fracture located in the PL quadrant, and type B was a cancellous fracture involving the PL tibial plateau resulting in a decrease in the posterior slope. One radiographic hallmark of this fracture pattern is an anatomically or a mechanically intact posterior column wall. The novel approach was applied to both types. The postoperative radiographic measurements revealed excellent reduction quality. On axial scans, the distance between the most posterior rafting screw and the tangent line of the tibial plateau rim was 3.0 ± 2.07 mm (from −1.9 to 4.3), and the angulation between them was 8.9 ± 3.02° (from −7.3 to 15.6). These results indicated excellent PL quadrant coverage from the rafting screws.ConclusionFlexion-valgus force-induced unicondylar tibial plateau depression fracture is a unique injury pattern. We suggest a novel surgical approach to address this injury’s key features, which may facilitate exposure and enhance fixation strength. 相似文献

PurposeThe aim of the study was to analyze the incidence of proximal avulsion of the five main ligaments and to revise the diagonal tension/compression concept in tibial plateau fractures.MethodsComputed tomographic images of 1263 cases of tibial plateau fractures were retrospectively analyzed by the OTA/AO classification and four-column nine-segment classification. The correlation between proximal avulsion of five ligaments and the injury mechanism was analyzed.ResultsIn total, 1263 tibial plateau fractures in 1253 patients were included. A total of 92 cases (7.3%) associated with proximal avulsions were identified among the 1263 tibial plateau fracture cases obtained from our institution's database. The 92 avulsions occurred in 82 patients, among whom 10 patients had two different avulsions in a single knee. The incidence of proximal avulsion fracture of the medial and lateral collateral ligament was 3.6% (45/1263) and 2.1% (26/1263), respectively. The incidence of avulsion of the anterior cruciate ligament and avulsion of the posterior cruciate ligament was much lower at 0.2% (2/1263) and 0.1% (1/1263), respectively. Proximal avulsion of the patellar ligament occurred in 18 cases (incidence rate = 1.4%). Several combinations of injuries, composed of distal tibial plateau fractures and proximal avulsion of ligaments, were identified.ConclusionsAmong the patients with tibial plateau fracture, the incidence of proximal avulsion of the five ligaments was 7.3% (92/1263). The four-column and nine-segment classification is an exhaustive method for recording injuries in these ligaments. The revised diagonal injury concept is useful for understanding the injury mechanism and choosing the appropriate surgical strategy. 相似文献

Background
Fractures of the tibial plateau are seen frequently in orthopedic trauma units and traditionally classified based on two-dimension plain radiographs with the Schatzker Classification system, the most popular. This system focuses on fractures involving the medial and lateral plateau but does not comment on fractures that involve the posterior aspect of the tibial plateau. The purpose of this study was to investigate the incidence of posterior tibial plateau fracture and propose a new computed tomography (CT)-based three-column classification system to guide fracture treatment.Methods
Between January 2008 and December 2009, 525 tibial plateau fractures admitted to a level 1 trauma center were retrospectively analyzed by four orthopedic trauma surgeons. Antero-posterior plain radiographs were used for Schatzker classification. CT imaging was used to further classify the fracture types with axial views dividing the plateau into three columns: a lateral, medial, and posterior. Posterior tibial plateau fracture (PTPF) was defined as a fracture with an independent fragment of the posterior columnResults
PTPFs were found in 151 cases and had an incidence of 28.8 % in this studied population. Except for type III, PTPFs were observed in each type of the Schatzker classification system. The Schatzker type VI, V, and IV fractures had the three highest percentages of PTPFs, with 76.1, 51.2, and 22.4 %, respectively.Conclusions
Fractures of the posterior tibial plateau are not uncommon, especially in high-energy trauma. CT imaging is required to appreciate these fracture patterns, and a three-column classification allows for a better understanding of the fracture morphology and the injury mechanism, which guides surgical management. 相似文献17.

BackgroundA posterolateral column fracture of the tibial plateau (PLCF) is not uncommon, especially lateral and bicondylar tibial plateau fractures. Currently, there is no consensus on the methods of surgical treatment for PLCF, including the surgical approach or the fixation strategy. Though various posterior approaches have been explored and can allow posterior buttress plate fixation, the necessity of a posterior approach with fixation for PLCFs is increasingly questioned. Meanwhile, there is no literature to analyse the morphological features of PLCFs. None of the available surgical techniques can solve all of the problems of PLCFs.MethodsFrom February 2016 to June 2016, an inconsecutive series of 16 patients who suffered Schatzker type II tibial plateau fractures involving the posterolateral column were selected based on an analysis of the morphological characteristics of PLCFs. The patients were all treated by lateral rafting plate fixation with magic screw implantation through the extended lateral approach.ResultsAccording to PLCF morphology, 4 patients had mild slope-type depression fractures (MSDF) of the articular surface, and the other 12 patients had block-type splitting fractures (BSF). After a 12-month follow-up period, there were no complications related to the fixation technique and no significant changes in limb alignment. At the final follow-up, the average range of motion (ROM) of the affected knees was 2.3°−125°, and the average HSS score was 94.2.ConclusionsThe selected patients who suffered Schatzker type II fractures involving the posterolateral column could be successfully treated via lateral rafting plate fixation with the magic screw technique. For PLCF treatment, magic screw fixation is a valuable technique that may reduce the utilization of posterior approaches and posterior fixations. 相似文献

ObjectiveTo prospectively study the outcome of surgically treated split depression lateral tibial plateau fractures extending into the posterior column using the extended posterolateral approach.MethodsTwenty-one patients with split depression lateral tibial plateau fractures (AO: 41-B3) with extension into the posterior column were treated with open reduction and internal fixation through an extended posterolateral approach with osteotomy of the fibular neck ± Gerdy tubercle. Follow up radiographs was assessed for quality of articular reduction and limb axis. Functional assessment was performed at last follow up using the Tegner–Lysholm score. Complications pertaining to the surgical approach were recorded.ResultsThe approach was performed in 15 patients with a fibular neck osteotomy alone and 6 patients required a Gerdy's tubercle osteotomy also. All fractures and osteotomies had united. Anatomical articular reduction was achieved in 16 patients. Radiological limb alignment was restored in all patients except for a reversed posterior slope in 1 patient. Arthritic changes were seen in 3 patients. The mean Tegner–Lysholm score was 87.3 (range: 76–95) at last follow up. No specific complications related to the surgical approach like common peroneal nerve injury and lateral instability of the knee was encountered.ConclusionThe extended posterolateral approach offers excellent exposure posterior to the fibular head to perform articular reduction and fixation achieving satisfactory radiological and functional results in split depression lateral tibial plateau fractures extending into the posterior column. 相似文献

BackgroundCurrently existing classifications of tibial plateau fractures do not help to guide surgical strategy. Recently, a segment-based mapping of the tibial plateau has been introduced in order to address fractures with a fracture-specific surgical approach. The goal of the present study was to analyze incidence and fracture specifics according to a new 10-segment classification of the tibial plateau.MethodsA total of 242 patients with 246 affected knees were included (124 females, 118 males, mean age 51.9 ± 16.1 years). Fractures were classified according to the OTA/AO classification. Fracture pattern was analyzed with respect to a 10-segment classification based on CT imaging of the proximal tibial plateau 3 cm below the articular surface.Results161 Patients suffered an OTA/AO type 41-B and 85 patients an OTA/AO type 41-C tibial plateau fracture. Females had an almost seven times higher risk to suffer a fracture due to low-energy trauma (OR 6.91, 95% CI (3.52, 13.54), p < 0.001) than males. In 34% of the patients with affection of the medial tibial plateau, a fracture comminution, primarily due to low-energy trauma (p < 0.001), was observed. In type B fractures, the postero-latero-lateral (65.2%), the antero-latero-lateral (64.6%) and the antero-latero-central (60.9%) segment were most frequently affected. Every second type C fracture showed an unique fracture line and zone of comminution. The tibial spine was typically involved (89.4%). A typical fracture pattern of high-energy trauma demonstrated a zone of comminution of the lateral plateau and a split fracture in the medial plateau. The most frequently affected segments were the postero-latero-central (85.9%), postero-central (84.7%), and antero-latero-central (78.8%) segment.ConclusionPosterior segments were the most frequently affected in OTA/AO type B and C fractures. Acknowledging the restricted visibility of posterior segments, whose reduction and fixation is crucial for long-term success, our findings implicate the use of posterior approaches more often in the treatment of tibial plateau fractures. Also, low-energy trauma was identified as an important cause for tibial plateau fractures. 相似文献
